Abstract (en)

The notch 17 is formed at one end of the board (12) and the two notches (18a and 18b) are formed at both sides of the other end. The first and second electrode patterns (13 and 14) covering, which cover the notches formed at both ends, are formed on the board surface, the light emitting diode (LED) chip (11) is connected to the first electrode pattern (13) and the electrode (11a) of the LED chip (11) and the surface electrode (14a) of the second electrode pattern (14) are bonded to each other with the metal wire (15). The LED chip (10) and the metal wire (15) are embedded with the translucent resin mold 16. Wire bonding on the surface electrode (14a) of the second electrode pattern (14) with the other end (15b) of the metal wire is made on the board 12 located between the two notches (18a and 18b). As a result, wire bonding can be made stably. Moreover, the polarity of the LED chip can be checked easily based on the appearance. Furthermore, handling jprocess can be performed smoothly. <IMAGE>
